Our Services

Bottom Pan Reconstruction & Condensate System Repairs

We reconstruct corroded or deformed bottom pans using marine-grade stainless steel to ensure proper drainage and long-term resistance to moisture, chemicals, and microbial growth.

Duct Construction, Modification & Repair Work

We fabricate and install all types of sheet-metal ducting used in marine HVAC systems. Our onboard repair services cover damaged sections, leaking joints, and performance-related issues caused by system degradation.

We install professional-grade thermal and acoustic insulation for pipes, ducts, and AHUs, using Armaflex and equivalent closed-cell materials designed for marine HVAC applications. Our insulation work improves energy efficiency, reduces condensation risk, and enhances environmental control.
